Déjà vu all over again. HBS' announced its R1 deadine for the Class of 2016 - and just like last year (2012) - this year submission day falls on September 16 (2013).
From the HBS Admissions Director's Blog post dated April 24, 2013:
"We'll be launching the application for the Class of 2016 at the end of May. Here's some advance info: The Round 1 deadline will be September 16. For 2+2 candidates only (rising college seniors), there will be a Summer Round with an application deadline of July 15."

HBS loves being out front, don't they? ;)
Not to be outdone, MIT Sloan's Jen Barba announced on the very same day (coincidentally):
"I'm actually working on the new essay questions this week, and hope to have those posted to the web by mid-May (need to get several approvals first). The actual application probably won't be available until mid-July."
